Question : Problem: New DDR2 RAM ... PC won't boot or POST

I need more RAM in my Vista machine.

I have a PCChips A13G+ v3.0 Motherboard with a 64-bit AMD processor.  Specs at:

I am currently running 1 1-GB DDR2 stick of memory.  It works fine, but I wanted to jump to 4 GB.
So I bought 2 2-GB DDR2 800 sticks. Specs at:
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2905800&CatId=3410

With those installed (or even just one of them), the system emits a series of high-pitched beeps, spins the optical drives, then just beeps.  It won't POST.

I pulled them out & replaced my 1-GB stick and all was well again.

What am I doing wrong w/ those 2-GB sticks?

Thanks!

Yeah swap them around anyway. RAM can be fussy like that.

Then if that fails and you dont have anything to test the RAM on i am out of ideas.

You really need to find another box with DDR2 ram so you can either pull out those ones to test in your machine or to test your DIMMs in that machine.
